Hello j_w_1234

do you use some kind of decluttering in your project?

check in this screen -> properties-> Layers

here in the table check the Minimum zoom factor and the maximum zoom factor of the layer

check also if the disapearing controls are on the same layer or as i suppose on different ones that uses different zoom settings
